STUDY OF JOINT OPENING EFFECTS ON THE DYNAMIC RESPONSE OF AN EXISTING ARCH DAM
Abstract eng: This paper presents the experimental and finite element studies on the effect of discontinuous behavior at the vertical contraction joints on the dynamic response of the existing arch dam. The variation of the resonant frequencies as a function of the reservoir water level is investigated. The measured dynamic properties are compared to predictions from finite element models, for which the nonlinear behavior due to the discontinuities of the vertical contraction joints are both included and neglected. The computed results demonstrate that the observed variation of the frequencies was attributed to a modification in the arch stiffness due to the nonlinear effect of the joints.
